Full Version: The Performance Dual Impact Gamepad for PS1 - Dualshock+neGcon Compatible Pad!

I got a Performance Dual Impact Gamepad, aka "Dual Impact Gamepad Colors" even though it's all grey so it isn't exactly very colorful, for the PS1 recently for $6. It's a pretty interesting gamepad -- for the most part it's just a decent Dual Shock clone, larger and not quite as well made as the real thing but very comfortable to hold due to its size, but it's got two unique features which make it a quite interesting controller to have.

Mine looks like this, except it's all grey, instead of being multicolored like that one. It also says "Colors" on it to the right of the logo; this model doesn't. I assume that internally the two are the same, and the button layouts are definitely identical. The key is that little switch in the lower middle. It's got three settings. Left to right, they are Digital, Dual Analog, and Wheel (neGcon). This controller does have vibration feedback, and it works in any of the three modes in compatible games. (Note that there's also Dual Impact 2, which is a PS2 controller, and does not have the neGcon mode. That looks like just your standard PS2 clone pad.)


As for this one though, its unique features are:

-First, there's a neGcon (wheel) mode, so the controller's left analog stick works with games that are neGcon but not Dual Analog compatible, such as Wipeout XL or Motor Toon Grand Prix. That's awesome, it makes Wipeout XL almost feel like a new game! Worth it for that alone. Unfortunately it didn't work correctly with Hardcore 4X4, which is a game that supposedly supports the neGcon/wheel, but that game plays great with the below mode, so there's that at least. That's probably the game's fault, though, given that Wipeout XL, Motor Toon, etc. correctly recognize the pad as a wheel/neGcon.

One very interesting point here is that the Dual Impact's neGcon mode IS Vibration compatible. That means that yes, you can play a racing game in neGcon mode on this pad, with rumble. Cool! :) The neGcon and wheels like the Mad Catz wheel do not have vibration, but this does.

Also, after testing it (see the list below), I found that in neGcon mode, the Dual Impact has a smaller deadzone than it does in Dual Analog mode, which means that games like Crash Team Racing and Wipeout 3 control a little bit better in neGcon mode than they do in Dual Analog. I assume that this is because the Dual Shock has a big deadzone (a flaw the Dual Shock 2 and DS3/Sixaxis both share.), but it's cool that in neGcon mode it's a better stick.

The only real negative about this mode is that the buttons aren't labelled for the neGcon's unique button labels, they're only labelled as standard PS1 controller buttons, so you just have to memorize that in the wheel mode X is I, Square is II, Circle is A, Triangle is B, L1 or L2 are L, and R1 or R2 are R. It's not too hard to remember though. I'm sure a real neGcon might be better than this, but those are extremely rare in the US, so I'd have to get it from EBay and pay a whole lot more than I did... and anyway, having an analog gamepad controller that supports neGcon/wheel mode is pretty cool! See the end of the post for a full list of how the game works in my neGcon-compatible games.


-Second, Dual Analog mode. It works as you expect, just like a Dual Shock pretty much. About the only negative versus a real Dual Shock, apart from the build quality/design changes, is that this has older-style small shoulder buttons, not the larger L2/R2 buttons the Dual Shock added. Too bad. Other than that though, works fine.


-And last (well, first, but I'm going backwards), Digital mode. While mostly this is as you'd think -- decent (non-missing-center) d-pad and buttons -- but interestingly, it's got more than just that. The controller's other unique function is that the analog sticks -- yes, both of them -- emulate the d-pad in digital controller mode. They aren't analog of course, but still, it's pretty interesting, and sometimes good, to be able to play dpad-only games with the stick... pretty unique feature, you see that on PC gamepads of course, but I've never seen it on any console gamepads... a few special console controllers can do that, such as the Sega Mission Stick for the Saturn and the Sega Sports Pad (trackball) for the Master System, but not gamepads... except for this one.

And yes, some games are more fun with the analog stick acting as a dpad than they are in digital mode. I'd ay that about Hardcore 4x4, for instance; the neGcon mode may be sadly broken, but in Digital mode with the stick, it plays quite nicely.


So, overall, yeah, it's an interesting controller. I like it. And yes, even if it clearly doesn't feel as well built as a first-party controller is, it's not too fragile-feeling, and is comfortable to hold, more so than Sony controllers are for me -- I find the Playstation controller too small. The only thing it doesn't have is Dual Analog Joystick support -- you know, the full-sized, twin-stick joystick for the PS1, (Yes, there are some games that only have analog with that; the Sony Dual Analog Gamepad has a mode supporting it, but no other gamepad I know of for the system does that.) -- but apart from that it's got everything else. In the end the Dual Impact is a good gamepad that I'm happy I got, mostly for Wipeout XL (It's SO much better now! Sure I have the wheel, but that's useless for this game.), but also for some other games too, and for the "analog stick usable in dpad-only games" thing too. Interesting stuff.



Dual Impact/neGcon Compatibility List
--
There are(definitely incomplete) lists of negCon compatible games here:
http://www.rolling-start.com/forum/viewt...?f=14&t=26 and here
http://www.mobygames.com/attribute/sheet...t,0/so,0a/
Of those, I list below my results when using the games I have with this controller. Note: I mean US releases of the games, not other ones. Also I would only care about games with twist support, of course; if it's just a "it uses the negcon but just the dpad", it's the same as it'd be with a regular controller.

Games with no Dual Shock support
--
Destruction Derby - Works fine.

Motor Toon Grand Prix - Works perfectly. Good controls this way, the game has no Dual Shock support.

Namco Museum Vol. 1 and Vol. 3 (in Pole Position and Pole Position II) - Works okay, though an actual wheel is better because of the much greater degree of motion -- with the Dual Impact, make VERY small movements if you want to not crash.

Ridge Racer Turbo (on R4 Bonus Disc) - Unfortunately, the Dual Impact doesn't work ingame with this game; the menus work, but it doesn't recognize it once you start playing. To get analog here, you need to use either a real neGcon, or a wheel like the Mad Catz wheel (the game does not have Dual Shock support).

TNN Motorsports Hardcore 4x4 - While my Mad Catz wheel works fine, so the game does have neGcon support, it doesn't work with this controller sadly -- left and right both turn you in lefthand circles, you can't go right.

Wipeout XL - Works perfectly, and is fantastic. This game doesn't have Dual Shock support, so something analog for it is essential! And an actual wheel is far too wide a turning radius for something like Wipeout; that may be better for car-racing games like Pole Position or Destruction Derby, but in a Wipeout game, you really want a stick like this one.

I can't find my copy of the original Wipeout, so I can't test that one. :(

Games with Dual Shock support (you may think that this would be identical to Dual Analog mode, but -- it's not! neGcon mode has a smaller deadzone than Dual Analog mode, so it makes it more precise than Dual Analog mode is in games that work with both. It's pretty cool, though this is more noticeable in some games than others, it's great!)

Atari Anniversary Edition Redux - Called "Wheel" mode ingame, this works for analog in paddle games like Warlords, Pong, and Super Breakout. Works fine.
Crash Team Racing - Works correctly in neGcon mode. Smaller deadzone is noticeable.
R4: Ridge Racer Type 4 - As with the RR Turbo Disc, it works in the menus, but not ingame. Bah!
Rollcage - Works correctly in neGcon mode. You can tell that the deadzone is smaller.
San Francisco Rush - Works correctly in neGcon mode.
Wipeout 3 - Works correctly in negCon mode. Smaller deadzone is noticeable.
Test Drive 4 - Works correctly in neGcon mode. This is awesome, because in Dual Analog mode, the game requirse you to use the right stick to accelerate/brake, and the left stick to move. I hate this control scheme, I want button acceleration/braking. You get that in neGcon mode. Awesome. :)
The Italian Job - Works correctly in neGcon mode.

etc., I'm not going to test every single driving game I have right now, though I may add to this list in the future as I test more games.

I do know some which definitely don't have neGcon support, though: Street Racer, JetMoto, and Dare Devil Derby 3D are digital-only for sure. Too bad. (JetMoto does have analog support in the PC version, but not on PS1.)

There are also some games that support the Dual Analog controller, but not the neGcon/wheel, such as JetMoto 2, Road Rash 3D, Driver, Circuit Breakers, and plenty more. Games where you need to tilt up and down, like Sled Storm, Moto Racer World Tour, the 1/2/3Xtreme series, etc., naturally also do not support a one-axis controller like this.

As for PS2 games, only a few support neGcon, but I do have Ridge Racer V. Even though R4 didn't work correctly with the Dual Impact, Ridge Racer V works perfectly with it. It's pretty much the same as regular analog control, but still, it's cool that it works.
Well that sure is itself. Thing is, I just don't see myself playing any of the "realistic" racing games. That's a whole genre I've basically just ignored, much like all sport games with the exception of NBA Jam once upon a monster.
I don't like realistic (like, realistic-handing) racing games either, but I do like analog controls in racing games... in something like Wipeout XL, analog versus digital makes a HUGE difference. And of course, that game's about as far from realistic as you can get.

As for why I have a wheel for the PS1, that's mostly because it was $5 at Goodwill. I almost never use it; I generally am better with gamepads.
